Beer nerds have been clamoring for a taste of the recent beer collaboration between Sierra Nevada and Dogfish Head breweries. Much like the Brooklyn Brewery/Schneider collaboration, the brewmasters swap or combine yeasts and apply them to their own recipes.

The collaboration between Sierra and Dogfish has yielded two brews: Life and Limb, and Limb and Life. Life and Limb is brewed with maple syrup using a combination of yeasts from both brewers, and naturally carbonated with birch syrup. This brew is available in 24 ounce bottles and on draft. With its intense sugar and 10 percent ABV, this one should pack quite a punch and age quite nicely.

Limb and Life is a descendant of the first brew, using its residual sugars, and then hopped. At 5 percent ABV, this is a gentler creature, and is only available on tap.

According to the Lagerheads, Whole Foods, Chevy Chase Liquors, The Brickskeller, RFD, and Birch & Barley are the best places to try and pick up bottles of Life and Limb.

But if you want to catch it on draft, Scion Restaurant will be hosting a tasting of Life and Limb (a.k.a. the big, bold one) this Sunday, Jan. 10 from 5-8 p.m. For $12, you’ll have a chance to taste Life and Limb along with both sweet and savory dishes. After that, the remainder of what’s on draft will be sold on a first come, first serve basis. You can reserve a spot at the tasting by emailing joanne@scionrestaurant.com.
